Is this data sharing a consequence of RealID, or were these requests made independently of that?
New York state declined, and is having Global Entry signups from that state rejected by DHS [1].
Edit: @crooked-v: Agreed, the administration found a straightforward way to the data other than via the census dept (it boggles the mind that people thought the federal government wouldn’t or couldn’t aggregate this data, remember when they withheld federal highway dollars to extort states into raising the drinking age?). Throttled by HN, can’t reply directly to your comment.

The purpose of the US Census has never been to determine citizenship. It's also fundamentally useless for that purpose, as not only is it entirely self-reported data, but it also cannot legally be accessed by other parts of the government until 72 years after that census is taken.
But the power stucture doesn't seem to care very much about law.
